How to have adaptive / transparent background UI Tab bar like app store in android

I was trying to work on a project which is required to have a tab bar with transparent background like iOS UiTabBar . Right now what happen is ,i can manage to have transparent background but content view is overlap with tab bar. In order to solve this , i give exact same height as tab bar so that i can scroll up and none of ui components are overlap . But i have tons of views in my whole project neither willing to add height to all pages. If there is other simplified and better way to do , pls give me some suggestion. Thanks
